SHAPING-MACHINE.

SPECIFICATION forming part of Letters Patent ecessary dated. July 31,1900. 4 Application filed February 7, 1600. Serial No; 4,334; illomodel.)

To all whom it rncoy concern:

ilton and State of Ohio, citizens of the United States, have inventedcertain new and use'-; ful Improvements in Shaping-Machines, of

which the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, which form a part of thisspecification.

Our invention relates to improvements in shaping-machines, and isdesigned to reduce the friction in the operation of the ram; to furnisha means by which the feed may be regulated at will without stopping themachine; to provide a means for varying the gear of the machine, so asto regulate the velocity of the rams travel, and to provide rear viewlooking at Fig. 1 from the right,

several parts being shown in section. Fig. 3 is a detail in section ofthe mechanism for controlling the feed. Fig. 4 is a section through Fig.3 on the line 4 4:. Fig. 5 is a detail view showing the mechanism forvarying the gear. Fig. 6 is a detail for the support for the table.

Referring to the drawings, A is the usual column or frame supporting theram B,which carries the tool mat'its forward end. The block 01 ismounted on the screw P, which is carried by the ram 13. I The block clis provided with a stud f, which passes through the slot 0' and has atits upper end the clampinglever e for clamping the block in any positionin the slot 0','so that the position of the tool on may bemoved forwardor backward without changing the length of the stroke of the ram. Thisis the usual manner of mounting the block t, so that it need not bedescribed further. Apin'c is secured in the lowerpart of the block cland is made longer than the width of the block, so that it sticks out atboth sides. Rollers b are loosely mounted on each end of this pin 0.Instead of the pin 0 the block d may be provided with lugs upon Be itknown that we, JAMEs C. SrnEN, re siding at Cincinnati, and PERRIN G MARCH, residing at Fernbank, in the countyof Ham which to mount therollers 19.

is pivoted in the usual manner in the column ,A at S and is provided atits upper end with,

the prongs E, which pass on each side of the block d; These prongs E areslotted, so as to receive the rollers b between the bearingfaces at. Weprefer to have this slot open at thetop; but of course it may be closedwithout departing from the spirit of our invention. As the arm 0 rocksforward and back its motion is communicated to the ram through therollers b, pin a, and block (1, the rollers 11 running up and down thebearing-surfaces a and turning on the pin 0, thus giving the effect of aball-bearing.

,Another improvement is a mechanism for changing the amount or directionof the feed or movement of the table-saddle along the cross-rail whilethe machine is in motion.

.F is the cross-rail, D the saddle, and E the table for carrying thepiece to be shaped. The cross-railF carries thefeed-screw g. (See .Figs.1, 3, and 4.) Loosely mounte'd on the feed-screw g is a rocker t,carrying a reversible pawl j. Said rockert' is operated in anyconvenientmanner', in this case by means of the connecting-rod Q andeccentric B, said eccentric B being geared in the usual manner to'themain driving-wheel G. A ratchetwheel his keyed to the feedscrew g and isprovided with a flange h, upon which is mounted loosely thecircular ringit, which has an' upwardly and outwardly projecting sleeve 76', designedto cover the teeth of the ratchet h. This sleeve 7c, however, onlyextends part way around the ratchet h, a portion of it being cut away,so as to leave a number of teeth of the ratchetuncovered,

this number being determined by the angle through which the rocker 11operates. (See Fig. 4,) The pawl j is of such a shape that theratchet,butwhieh rests upon the outer hasacollar n which, is "rooved soas to resurfaceofthe rocker when not intended to engage theratchet andholds thepawl j away from the ratchet, as shown in Fig.3. Thecoil-springt' holds the pawl j in engagement With .the ratchet when nototherwise. prevented. The ring Zchas aprojectingrim'k",

which is milled for ease in turning it, and it is loosely supported inthe bracket Z, which embraces it at one end and has its other endsecured-in any convenient manner to the rail F. p The ends of the sleeve70 are chamfered. ofi, so as to permit the pawl j to easily ride fromthe ratchet to the's-leeve. Itis readily seen by a glance at Fig. 4 thatby reversing caused to turn in either direction,thus causing the feed tobe in either direction. Now.

I suppose that the whole movement or throw of the rocker 2' causes toorapid afeed and that we wishto diminish the-feed. We simply turn theinilledhead 76'. so that the pawlj in rock ing .back to take hold againwill ride up on the sleeve 70'. Then when it rocks forward again it willnotengag'e the teeth of the ratchet until it passes the end of thesleeve 70, or until part of its forward motion has been completed. Itwill be readily seen that in this way the feed may be regulated anywherefrom the full movement of the pawl j to nothing at all, because if thesleeve k is turned far enough the pawlj will be in con-, tact with thesleeve 70 for the full length of itsmotion and will not engage the teethof the ratchet at all. The feed may be varied in the same way when the'pawl is turned in the opposite'direction. I

In doing heavy workit is sometimes necessary to support the table E, andfor this purpose we provide a-base a, which is secured tothe bedv of themachine. This base u. is'threaded on its inside to receive the screwt,and i-tissplit near its top and pro-' vided with ears at, throughwhich passes the bolta! for clamping the screw 15, so as to prevent itsturning. A block w fits loosely in a socket in the head of the screw t.and is pro- When a heavypiece of work is to be put onv the table E,thescrewt is run up in any con-x venient manner until the roller '0 isincontactzwith the bearing-surfaceE", and then the notion" onthe bolt 00is tightened, so as to prevent anyrotation of the screw and consequentlowering of the support.

To increase the number of available gears foroperating the ram B, weprovide the followingmechanismz I is the. main driving.

reetion along the shaft I. The gear-wheel n tongues projecting from theflange m.

ce ve the block .9. fiaid'collar has a flange n". The flange n" hasopenings into which fit This arrangement simply constitutes a clutchingdevice and may be replaced by any other clutching mechanism. Fulcru-medon'a-pla'te 7, which is secured tothe semen of the-machine, is the leverq, carrying thehan'dle g at its outer end and being pivoted at'itsforward end at q to the block 8, so that the gear-wheel n may be movedalong the shaft Iin either direction by moving the lever q. second shaftJ -is' provided, to which are "keyed the gears 0 and'p, 0 being designedto the position of the pawl j the ratchet maybemesh with the gearn whenit is in proper position and p meshing with the loose gear m p'andthrough it the gearG. Now suppose it is wished to decrease very much thespeed of thearm O. The lever q is shifteduntilthe gear 11 meshes withthe gearo, at the same time releasing its clutch wi.th -thegear m.

Now the gear a turns the gear o'onctheshaft J, which causes the gear 10to rotate, and thus rotatesrthe gear. G. Of course the gear m turnsalso, but being loosely mounted on the shaft I its turning has noefiect.I vAs is.readily seen,- this shiftingdevice for multiplying the speed,in connection withthe drivin g-cone,

gives a great variety of. speeds at which] the arm 0 may beoperative. I
